So sorry to hear about your Mom. I had breast cancer 9 years ago. But I caught it in time and only had to have radiation. It just made me real tired. I found the lump on a Friday night, got to the doctor on Monday, specialist and mammogram that same week. Had surgery the following week. It had not spread to any nodes, All I can do or say right now to you is be there for your Mom. I have heard of these new treatments and so far everyone I have heard of are fine. I will put you both on my prayer list. Hang in there. As I said it has been 9 years since I had mine. Take care. will look on the healthnet for an update on your Mom.
